WORK-SUPPORT.

Specification of Letters Patent.

Patented May 9, 1916.

. Application filed July 11, 1912. Serial No. 708,908.

To all whom it may concern Be it known thatI,MIo1-IAnL FRANK Bno-.

GAN, a citizen of the UnitedStates, residing at Lawrence, in the countyof Essex and State of Massachusetts, have invented certain ImprovementsinivVork-Suppmts, of

which the following description, in 'connec tion with the accompanyingdrawings, isa specificatlon, like reference characters on the drawingsindicating like parts'in the several figures.

This invention relates to i work' supports for holding boots and shoesin position to be operated "by shoe machines and is herein shown anddescribed by way of exemplification as particularly adapted for'support-,. ing shoes for the operation of aheelbreasting machine. 7 aj, r

The heel breastlng operation consists n removing the surplus materialfrom the front face'orb'reast of the shoe heeland is generally performedby a machlne having a knife mounted for vertical reciprocation, the

transverse center of the heel portionlof the last but is displaoedto onesidein a right last and to the'other sidein a left last. It isaccordingly necessary to provide lateral movement of the last relativelyto the knife so as tobringthe center of the knife to the center of theheel. In some styles of heels,

moreover, particularly high heels, it is usual' to make the.angle'between thebreast and shank somewhat acute and to efiect this result the forepart 'of'the shoe iselevated-to' locate the' heel at theproper angle to the knife, theylast'being so mounted asto permitthismovement. It is found, however,

when high heels are placedat a great inw,

clinationv to, the knife the line of pressure exertedby the knife is aptto fall to the rear of the transverse; axisabout which the shoe is,tilted, thereby causing the "forepart ofthe shoe tof rise withconsequent failure of the breasting operation and liability of injury,to the heel. I a j u j, 7

. It'is-the object fthis invention to pro vide a last pin mounting for awork support which, while compact enoughto enter 'means for turning theworm tohadjust the the smallest shoe, will provide the necescenter'oftl1ebreast to the center of the knife, and also allow movements of theshoe 1n a vertical plane to enable any desired inclinationlto be givento the breast face relatively t the trade'face of the heel.

- An important feature of the invention consists in aflast pin which ismounted on a support for movement in a vertical plane about a transverselocated adjacentto the lower end of the last pin, that is, approximately at the crownof the last. For

this purpose the support comprises two parts connected by asegmentalguide and NEXV' JERSEY, A CORPORATION: OF

This construo' tion'enables the pin to beplaced at various anglesto thepla'ne of the knife so that the breastface may be given any desired inclif nation relatively to the tread faceof the heel, and obviates any danger of the line of aotionjof the. knifefalling back ofithe.

The construction of the mounting. is so compact that the top or leg of asmall shoe may be placed over it in-putting thelast upon the last 7 pin.As shown, the last pin mounting consists'of a base adapted to be so iAnother feature of theinventionconsists secured to a jackpost or. othersupport, (a.

last pin carrier, and an intermediate I section located betwo n fiCarrier andthe with the accompanying drawings, and will be pointed outin the appended claims.

In the drawings, Figure 1 is a perspective view of thework support withthe breasting knife shown in dotted lines;'Fig. 2 is a central sectionof the devicepartly in elevation;

Fig. 3 is a similar View of a modification. The herein shown embodimentof'the invention comprises a base portion 2 which is adapted to beclamped upon the upper end of a jack post by a set screw In the upperend of the base 2 a T-shapedguldeway 6 is formed which is arranged toextend in the direction of the knifeedge, indicated' at w, Fig.1. In theT-shaped guideway of the base 2 is fitted a T-shaped guide 8 upon anintermediate section 10. A notch is made in oneside of one of the ribsof the T-shaped guide 8 to receive the end ofa set screw 12. whichlimits the movement of the guide 8 inthe base 2 and may be re moved whenthe parts are to be detached.

The intermediate section lO'comprises two.

portions or'blocks 14 and 16' which are connected together by a-T-shaped segmental I guide 22 and corresponding 'guidewayi'20,

the guide 22 being upon the upper portion 14 of the intermediate section10. The movement of the guide 22 in the guideway 20 is limited'by a setscrew 24 in a manner similar to that already described for thestraightguide 8. In the upper portion 14' of the intermediatesection 10 is asecond straight T-shaped guideway 26 which Is arranged in the'samedirection as the guideso that theaxis of the cylindrical hole in the way6, and a T-shaped guide 28 formed on a block 25' which constitutes thecarrier of a last pin 32 is arranged'toslide freely in said guideway;Movement ofthe carrierfguide 28 in its guideway'is limited by a, setscrew 30 which'enters a notch in the last pin carrier guide .28. 'Thelast pin 32-is securedin the carrier 25 and at its lower end withregard'to its exposed portion is a collar 34, upon which the end of Ithe last thimble or the crown of the, last rests when'the last is placedon the pin. The last pin 32 is tapered and is somewhat smaller than thehole in the thimble of the ordinary last. This looseness is p rovidedthimble need not coincide'exactly withfthe axis of the pin, and theconvex upper face of a collar 34 serves to support the end of thethimble with the axis of the thimble at varying inclinations to the axisof the pin.

In use, the base 2 having been secured firmly to the jack post with thestraight slides extending transversely of the shoe or in the directionof the plane of the knife, the shoe is placed upon the last pin orspindle and the jack swung under the operating parts of the breasting orother machine. As the thimble of the last is not usuallv in the centerof the heel portion of the last, that is, is not under the center of theheel seat, the shoe may be moved laterally by reason of the straightguides until the'center of the heel is opposite the center of theoperating instrumentalities of the machine, as for example the presserplate and knife of the heelbreasting machine; The shoe may be tiltedvertically about the axis y of the segmental guide which axis liesapproximately-at the crown of the last until the breast is at the properinclination to the knife or operating means. The center of movementof'the segmental guide is also approximately at the base of the lastpin, and therefore, it is practically im- 7 possible to incline the shoeto such a degree as to throw the line of pressure of the knife back ofthe axis of the segmental guide. If desired, the segmental guide may befixed at any inclination by means of a set screw 36, Fig. '2.

In order to permit ready adjustment of the angle of theheel pin'onthesegmental guidewayl the modification shown in Fig. 3 mayfb'eemployed inwhich the lower face of the segmental guide 22 is formed with worm teethand a worm 38"is journaled'in the lower portion 16"of the intermediatesection 10 in a position to engage the teeth on the segmental guide. Theworm is provided with a thumb head 40 by which it may be readily turnedto adjust the inclination of the last pin 32.

Having described my invention, What I claim asnew and desire to secureby'Let ters Patent of the United'States is i '1. In a last pin mountingfor shoe supports, the combination with a base of a last pin carrier, alast pin mounted thereon, and
